(01520-5691) The present invention relatesto improvements spaced apart from one another, and formed of in'windowglass mountings for store front conextruded metal. t struction of theclass consisting'of front and rear The blocks supporting the rear sashmember sash members between which the glass is sup- 3 are formed with aback wall 4 and a base wall 5 ported ajionggthe oppositeumarginal sideedges 5 secured by screws to the sill 1, and are also 60 thereof.provided with a top wall 6 formed with an upper As commonly constructedthe sash membersare drainage trough '7, and side and edge supportsoperated by a series of screws adapted to exert for the glass, indicatedrespectively by 8 and 9, considerable 'lo'cal pressure that tends underorthe glass being shown at 10. A locking lever 11 dinary conditions tocheck orcrack the glass. is pivoted at one end in a socket 12 formed in65 l in which the various featuresof the invention are T e Objeets Ofthis t on include mea s for the back wall 4, and intermediate its endsthe regulating the screw actionsin a manner to avoid lever is formedwithaprojecting lug 13 adapted breaking the glas and at the same timeaffording to be releasably engaged by an operating screw 14.

In assembling the parts, the screws 14 being released, the process isreversed by placing the glass upon the edge supports 9 and inwardlysliding the front sash members together with the fixedly connected arms1'7 over the outer face of sill 1 and the base members 5 of the rearsash members, the inward movements of arms 1'7 serving by means ofengagement of the inclined surfaces 17b thereof with the front beveledsurfaces 111) of levers 11 to automatically raise and pass under thelocking end of said levers, allowing the latter to fall by gravity uponsaid arms intermediate the length thereof. Also in the inwardly slidingmovements of the front sash members the upper clamping members 15thereof exert a manual pressure against the front marginal edge of theglass in opposition to the corresponding lateral support 8 of the rearsash members, the said manual pressure from the front sash members beeing sufficient to adjust and hold the glass without injury thereto, andin which position the opposite sash members are detachably lockedtogether against accidental displacement and independently of saidmanual pressure by the locking members consisting of the base wall 5,arm 17, lever 11 and screw 14, the said levers, arms and base membersbeing shaped to receive from the screws their full locking pressurewithout disturbing the relative position of the front sash members withrespect to the latters manual pressure against the glass. Variablethicknesses of the latter are also provided for by the self-adjustingaction of the locking members shown as controlled by the variablepositions of the front clamping face of the glass.

As indicated in Figs. 1, 2 and 3, 2a and 3a, respectively represent therelatively thin outer metal surfaces of the pair of sash members, andextending lengthwise at the base of leg 16 a groove 16a. is formed thatserves to fix the position of the blocks within the outer shell of thefront sash member by means of indentations extending from the thin outerwall into said groove, and for a similar purpose indentations or notchesare formed along the free edges of the socket 12 on opposite sides ofthe relatively narrow lever 11 to laterally position the same within therear sash member, and in alinement with the screws 14.

In Fig. 3 the blocks are shown as cut into relatively short lengths fromlong lengths of ex.

truded metal, each block constituting a complete operative unit adaptedto act through the outer shell to secure the glass without danger ofinjuring the latter, while in Fig. 4 relatively long metal lengths areemployed without the outershells and are similarly operable'to locl themembers together with spaced levers and screws as shown.

It is to be understood that while I have illustrated and described thepreferred embodiment of the invention, it is susceptible of variouschanges as regards its form, proportions, detail construction, andarrangement of parts without departing from the essential spirit andscope or sacrificing any of the advantages of the invention.

I claim:

1. In a glass mounting, a fixedly supportedprovided with a projectingarm engaging said.

base wall. a lever pivotally supported within said rear sash member, andmeans acting through said lever to clamp said arm to said base wall.

2. In a glass mounting, a fixedly supported rear sash member disposed toengage the rear marginal edges of the glass and provided with a basewall, a front sash member disposed to engage the front marginal edges ofthe glass and provided with a projecting arm engaging said base wall, alever pivotally supported within said rear sash member, and a screwengaging said lever and acting therethrough to effect a clampingpressure between said arm and base Wall.

3. In a glass mounting, a fixedly supported rear sash member disposed toengage the rear marginal edges of the glass and provided with a basewall, a front sash member disposed by manual adjustment to engage thefront marginal edges of the glass and provided with a projecting armengaging said base wall, a screw actuated clamp lever disposed todetachably lock said arm to said base wall and thereby secure said frontand rear sash members together as positioned by said front sash member,and means upon the release of said lever for disconnecting said frontsash member for the release of the glass.

4. In a glass mounting, front and rear sash members composed ofrelatively thin metal outer Walls, said rear members being fixed and thefront members removable, reinforcing blocks disposed within said frontand rear members, the blocks of said rear members having supportingmeans for the rear marginal faces of the glass and provided with basewalls, the blocks of said front members having-supporting means for thefront marginal faces of the glass and provided with projecting armsdisposed to engage the base walls of said rear blocks, means formanually adjusting the inward position of the front sash members andblocks with respect to the glass, and means for locking said arms andbase walls together as positioned by the manual adjustment of said frontsash members.

5. In a glass mounting, a fixedly supported rear sash member disposed toengage the rear marginal edges of the glass and provided with a basewall, a front sash member manually disposed to exert a clamping pressureon the front marginal edges of the glass and provided with a projectingarm having its free end slidably engaging said base wall, a leverpivotally supported at one end within said rear sash member, and a screwengaging said lever and acting therethrough to clamp said arm to saidbase wall and lock said front sash member as manually positioned withrespect to the glass.

6. In a glass mounting, a fixedly supported rear sash member disposed tosupport the rear within said rear sash member, and means acting 7through said lever to clamp said arm to said base wall and lock saidfront sash member as manually positioned with respect to the glass.

7. In a glass mounting, a fixedly supported rear sash member disposed toengage the rear marginal edges of the glass and provided with a basewall, a front sash member disposed for manually urged engagement. withthe front mar- 3 the release of the screw action of said lever the frontsash member is free to be slid outwardly or inwardly to automaticallyraise and lower said lever and respectively release and reposition saidfront sash member and locking parts.
